Voltage and frequency deviations in exemplary ship's network - research for ship owner

The paper is focused on a problem of electric power quality in ship electric power networks. Some current standards relevant to the discussed problem have been presented but the main part of the paper has described the research of voltage and frequency deviations on chosen ship. This research has been carried out on the ship owner request due to unusual steady-state frequency deviations from its rated value. Finally, the supply voltage parameters have been monitored during one exploitation trip and some conclusions for future undertakings have been drawn. This paper is based on original report for the ship owner and results of the research are given on the basis of the ship owner permission.
